My occasional technical diary of thoughts, tips, and tools from some of the more interesting things I'm playing around with at the time. That means all things Cloud, Open Source, Rails, BigData, Mobile, or just my latest rant.. who knows!

Tom Fishburne perfectly captures the reality of how many big companies really work. This may be painfully funny, but sadly I don't think it's all fiction...

Heinlein packs this atomic moonshot adventure with just about every Boy's Own plot twist possible and tells a rollicking ripping yarn. What's amazing is the detail of the hard science throughout the book - especially given the fact it was written in 1947.

All the shucks, gee willikins is quaintly pre-baby boom, while the embracing of atomic power with such wild abandon is frightening in retrospect. Altogether, it's a great - if dated - story; a true testament to Heinlein's genius and imagination.

On atomics: it is possible the tide of opinion may be swinging back to nuclear. The ABC Science show just featured a story on the safer and cheaper generations of reactors coming online (transcript, audio). Today's generation III reactors, and the generation IV on the horizon offer even cheaper, safer and cleaner power (literally eating the waste products of earlier designs). All well and good, but it would be a concern if "new atomics" became the quick and easy fix that sabotages the head of steam building up behind the true clean, green renewables (like solar nanopillars).

So this weekend I've dressed up jTab as a little web application to help you learn chord fingerings for guitar...

Introducing the ChordMaster 2000 ;-)

OK, so maybe I sexed up the design and UI a little too much for such a simple task, but it was fun to see how far I could go with javascript and SVG (and no flash or silverlight).

It was also a proof point for jTab - the javascript library I released last week that renders arbitrary guitar chord and tab using SVG. Happily, it worked fine without a tweak - just some extension methods that are specific to the ChordMaster application (like getting an array of all chords that are defined as "intermediate" level).

PS: big thanks to @jasonong who's jumped in and already made some great contributions to the jTab project on github -- It's amazing to see github rock as a "social coding" platform - create a public project one day, have changes to merge back the next. Trivial to do with git, and the great visualisation of the project revision/branch history makes merging so easy to understand.

Guitar tab (notation) is all over the internet, but it is usually in either a fixed/non-interactive form, or painstaking ASCII format.

I've always wanted a better way, and two things I've looked at recently inspired me to think it might be possible: Dmitry Baranovskiy's fantastic work on the Raphaël SVG library, and Alex Gorbatchev's syntaxhighlighter.

So now I can introduce the result of my latest weekend project:

jTab - newly minted and ready to rock and roll!

See the project home page at http://jtab.tardate.com for more examples and information about how you can use it too. jTab is open source, with the master source code repository on github .

What does it do?

jTab is a javascript-based library that allows you to easily render arbitrary guitar chord and tabulature (tab) notation on the web. It handles implicit and automatic rendering of any page elements given the special class name 'jtab'. It can also be scripted for more sophisticated or interactive effects.
